为有效消除电力电子设备的谐波干扰,基于UC3855设计了BOOST功率因数校正电路。主电路为减少功率损耗采用ZVT零电压辅助开关。控制电路采用双闭环平均电流模式。利用乘法器校正使输入电流接近正弦波并保持与电压同相位。通过小信号建模推导了电流环、电压环传递函数,配置了系统双环补偿校正网络的参数。最后通过MATLAB仿真和实验验证了设计的正确性。系统的动、稳态性能良好,功率因数接近为1。

In order to decrease the interference of harmonic in power electronic devices effectively, this paper proposed a BOOST Power-Factor-Correction circuit based on the UC3855. The main circuit uses the ZVT Zero-Voltages-Switch attempt to reduce the power loss. The part of control uses the Double loop average current mode. The function of multiplier is to make the input current approach a sinusoidal, and keeping the AC input current in phase with voltage. In this paper, we give the transfer function of current loop and voltage loop through a small signal model, assigned the parameters of Double compensation network. Finally, we proved the efficiency of proposed method through MATLAB simulation and experiments. The dynamic and static performance of thi...
